My family has an early education class once a week, four times a month, and a semester lasts for three months, with a total of 12 classes in January 120 yuan. I handed it in for one semester at a time, and received my 300 yuan after a discount. It works out that each class is 25 yuan. This may be a very cheap price in economically developed areas, but this is an economically backward area, and this price is neither high nor low.
